A crash at Norsewood three weeks ago landed a Hamilton woman in Dannevirke District Court on Friday.
Shaquoia Rangiwhetu, 22, was charged with careless driving causing injury, but this was amended to careless driving.
Counsel Darren Foster said Rangiwhetu held a learner's licence and had no previous convictions.
At the time of the accident, Rangiwhetu had her sister and her niece in the car.
She hadn't had much sleep the night before and fell asleep at the wheel.
